T 0 all whom it may concern: 7

Be it known that I, PLnAs E. VINEYARD, a citizen ofthe United States,residing at Windom, in the county of F annin and State 5 of Texas, haveinvented new and usefullmprovements in Accelerators, of which thetollowingis a specification.

This invention relates to improvements in motor driven vehicles and hasespecial relation to means for controllingthe supplyof fuel to internalcombustion engines, an object being to provide toot operated means forthis purpose which is especially designed for application to automobilesof the well known Ford make. 7

Another object of the invention is the provision of a foot acceleratorwhich may be attached by means of the bolts already present in theautomobile mechanism, so that the services of a skilled workman ormechanic will be unnecessary for the application of the invention. I

Another object of the. invention isthe provision of means included inthe accelerae tor structure, whereby the foot pedal may be operatedwithout moving the hand throt tle lever, novel means being provided forattaching the device to the throttle-valve,

controlling arm of the this purpose. I a

Another object of the invention is the provision of means whereby theusual rod which connects the hand lever rodto the carbureter, may beadjusted, so as toproperly control the operation of the throttle valvewith the hand lever.

With the above and other objects in engine earbureter for view,

the invention further includes the follow-I ing novel features anddetails of construction, to be hereinafter more fully described,illustrated in the accompanying drawings and pointed out in the appendedclaims.

In the drawings 2-- Figure 1 is a plan view showing a fragmentaryportion of an automobile mechanism and a portion of the floor of theautomobile.

Figure 2 is a fragmentary side view of the same with the portion of thefloor shown in Figure 3 is a detail plan view illustrating the means ofconnecting the foot accelerator pedal and the hand lever with the arm ofskilled wo-rl'n'nan for its attachment.

this purpose there is provided a plate the carbureter throttle valve,the parts be ing in normal position. o Figure 4 1s a view similar toFigure :8

showing the position or the parts when the I throttle valve is operatedby the hand lever.

I Figure 5 is a like view showing the posi tion of the parts when thethrottle valve is operated by the foot pedal.

. Figure 6 is a detail plan view illustrating the manner of attachingthe hand lever rodv to the carburetor connecting rod.

Figure '12 is a detail perspectiveview of the pivoted arm.

I Figure l3'is a section taken substantially onv the line 13+-13 ofFigure 4.

15 indicates a portion of the housing-of an:

internal combustion engine, which is supported upon side bars 16'of theframe of the automobile, while 11 indicates the transmise slon casewhich is located between the fioor 18 of the auto-mobile body, the usualclutch,

reverse and brake pedals extending upward ly throughthis floor as shownat 19.

The present invention provides foot operated means for controlling thecarburetor throttle valve, which is mounted so as not to require theservices of a mechanic. or

which is disposedtransversely beneath the floor 18 and which has securedthereto as shown at 21, one end of an arm 22. The opposite'end of thisarm is secured upon one of the screws: or bolts 23 which serve to securethe cover of the transmission case 17 in place and for this purpose, thearm 22 is: provided with two openings one or which may be brought intoposition for re ceiving the screw or bolt 23 of the late model Fordautomobile,'while the other is designed for use with previous models.The connection 21 between the arm and the plate 20 is therefore pivotal.Rlgldly secured to the plate 20 is one end ofan arm" 25, while theopposite end of this arm is notched as at 26 so as to receive one of thebolts 27 of the engine head.

The plate 20 is provided with spaced bearin gs 29 within which ismounted a rock shaft 30, the said sh att carrying at one end a crank arm31. Adjustably secured to the opposite end of the shaft 30 as shown at32 is a foot pedal 33 which extends upward through a slot 34- providedin the floor 18, the adyush able securing means 32 providing conven1entmeans for properly positioning the pedal 33 upon the rock shaft toinsure proper operation of the parts.

The engine carbureter which is of the ordinary construction is indicatedat 31 and is pr vided with the usual operating arm 35 which is rigidlysecured to the stem 38 0? the throttle valve. The arm35-is provided atits free end with an opening 37 which ordinarily receives one end of aconnecting rod 38, but in the present invention this rod isremoved and abolt 39 is positioned in the opening 37 which serves as an attachingmeans for a clamping arm 40. The arm 40 has extending downwardly fromopposite side edges fingers or lugs 41, whicl'i engage the oppositesideedges of the arm 35 and act to hold the clamping arm 40 rigid withrespect to the throttle valve operating arm 35.

The free end of the clamping arm 40 carries a substantially L-shapedrigid arm 42 which is provided at its outer end with an opening 43 forthe reception of one end of a rod let, while the opposite end of thislast mentioned rod is pivotal-1y secured to the outer end of the crankarm 31.

As thus far described, it will be apparent that with the parts in theposition shown in Figure 3, a downward pressure upon the foot pedal 33Will rock the shaft 30 and move the rod'es forward as indicated by thearrow 1n Figure 5 01": the drawings and thus actuate the throttle valve.

end of this arm is provided with a slot 47.

This-slot is adapted to receive one end of the rod 38 which isordinarily connected to the rod 48 which has secured thereto the usualhand lever (not shown).

In order to accommodate the rod 38 for use with the present inven f onthere is provided a plate 49 which is illustrated in Figure 6 of thedrawings and which is provided with an opening 50 for receiving the endof the rod 38. This plate 49 is provided with a slot 51 for the passageof a bolt 52, which bolt serves to connect the plate 49 with the usualarm 53 which is carried by the rod 48, the plate 49 may thus beadjustable upon the arm to accommodate the rod 38 to the dili'crencebetween the connecting means of the present invention and that usuallyemployed.

hen the hand lever (not shown) is operated to control the throttlevalve, the rod 48 will be rotated in the usual way, which operation willmove the rod 38 in the direction of the arrow shown in Figure a,whereupon the end of this rod which is connected to the pivoted arm aswill engage the clamping arm 40 and operate the throttle valve. Whilethe rigid arm 4:2 and consequently the foot pedal 33 will also beactuated, it will be apparent that the said foot pedal may be operatedto control the throttle valve without actuatingthe hand lever.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope or" the appendedclaims.

Having described the invention what is claimed is 1. The combinationwith an automobile having an internal combustion engine, of a bearingplate extending transversely beneath the floor, of the automobile, anarm having one end connected to the plate and its opposite end securedto the engine, a second arm also having one end secured to the plate andhaving its opposite "end secured to the transmission case for supportingthe plate, rock shaft mounted in bearings carried bythe transverseplate, a foot pedal seeuredto the rock shaft and extending from thefloor and means operatively connecting the opposite end of the arm tothe throttle valve of the engine carbureter for operating said valve 7 a2. The combination with an automobile having an internal combustionengine and a hand'lever for controlling the throttle valve. of theengine carbureter, of an arm rigidly secured to the throttle valveoperating arm, a rock sl1al't,a foot pedal secured to the rock shaft,means operatively eonnect ing the rigid arm and rock shaft, whereby thethrottle valve may be operated, an arm pivotally mounted upon the rigidarm securmg means, a rod having one end connected to the pivotallymounted arm and adjustable means connecting the opposite end of said rodwith the throttle lever rod.
